Tripundra investors: How do you *really* check builder history?

Builder ka delivery track record check karna is the real game-changer for investors, especially with projects like Tripundra. I just got possession of my flat last month, and things nobody told me about builder delays really hit hard. For Tripundra, have you guys actually looked at their previous projects' *actual* possession dates vs. promised? This directly impacts rental yield and resale potential, right? Koi batao, is the resale market for their completed projects liquid? I'm worried about being stuck.
